The successful candidate will thrive in laying down technical foundations from scratch, ensuring scalability, maintainability, and high performance for our data and data science workflows.

What You Will Do:

• Collaborate closely with Data Scientists and Data Analysts to translate experimental code into production-ready architectures, driving code refactoring, model hosting decisions, and seamless integration.

• Design and formalize end-to-end model deployment processes , establishing standardized workflows for model versioning management to ensure reproducibility and reliability in production.

• Build and maintain robust data pipelines leveraging modern big data and distributed processing ecosystems, while establishing standardized Data Science development environments to boost cross-functional team productivity.

• Implement foundational ML infrastructure and standards , including feature store integration and data versioning management, tailored to support scalable business growth.

• Develop and operationalize predictive solutions using appropriate statistical, analytical, or heuristic approaches , when business needs require, bridging analytical insights with operational execution.

• Monitor, maintain, and optimize existing deployed solutions , proactively identifying bottlenecks, addressing technical debt, and ensuring high availability of production models.

Basic Qualifications

• Bachelor's/Master's degree in computer science, software engineering, industrial engineering, or any other quantitative disciplines, with 5+ years of relevant software/ML engineering experience in industry

• Hands-on experience in MLOps and model deployment lifecycle, including code refactoring, containerization (Docker, Kubernetes), and model hosting strategies (e.g., FastAPI, REST APIs, or cloud-native endpoints)

• Solid proficiency in Python, SQL, and distributed data processing frameworks (e.g., Spark, Hive, or equivalent big data technologies), with proven experience in building and maintaining scalable data pipelines

• Practical experience in setting up and standardizing ML foundations, such as feature stores, data versioning tools (e.g., DVC), and model registry/versioning management systems

• Strong software engineering best practices, including version control (Git), CI/CD pipelines, code testing, and clean architecture design

• Excellent written and verbal communication skills to effectively collaborate with Data Scientists, product managers, and software engineering stakeholders

Preferred Qualifications:

• Demonstrated experience working side-by-side with Data Scientists in an applied research or advanced analytics environment

• Familiarity with building and deploying lightweight or moderate-complexity machine learning models (e.g., forecasting, classification, or regression tasks)

• Experience evaluating and implementing internal tooling and lightweight frameworks to streamline DS workflows and accelerate time-to-market

• A deep understanding of the e-commerce or supply chain domain, with a track record of driving scalable engineering solutions that deliver measurable business impact
